The X-ray Free-Electron Laser facility, SACLA, has delivered X-ray laser beams to users from March 2012 [1]. Typical user experiments utilize two-dimensional-imaging sensors, which generate 10 MBytes per accelerator beam shot. At 60 Hz beam repetition, the experimental data at the rate of 600 MBytes/second are accumulated using a dedicate data-acquisition (DAQ) system [2]. To analyze such a large amount of data, we developed data-analysis system for SACLA experiments. The system consists of on-line and off-line sections. The on-line section performs on-the-fly filtering using data handling servers, which examine data qualities and records the results onto the database with event-by-event basis. By referring the database, we can select good events before performing off-line analysis. The off-line section performs precise analysis by utilizing high-performance computing system, such as physical image reconstruction and rough three-dimensional structure analysis of the data samples. For the large-scaled image reconstructions, we also plan to use external supercomputer. In this paper, we present overview and future plan of the SACLA analysis system.

X-ray imaging detectors are indispensable for synchrotron radiation experiments and growing up with larger number of pixels and higher frame rate to acquire more information on the samples. The novel detector with data rate of up to 8 Gbps/sensor, SOPHIAS, is under development at SACLA facility. Therefore, we have developed a new front-end DAQ system with high data rate beyond the present level. The system consists of an FPGA-based evaluation board and a FPGA mezzanine card (FMC). As the FPGA interface, FMC was adopted for supporting variety of interfaces and considering COTS system. Since the data transmission performance of the FPGA board in combination with the FMCs was already evaluated as about 20 Gbps between boards, our choice of devices has the potential to meet the requirements of SOPHIAS detector*. We made a FMC with Camera Link (CL) interface to support 1st phase of SOPHIAS detector. Since almost CL configurations are supported, the system handles various types of commercial cameras as well as new detector. Moreover, the FMC has general purpose input/output to satisfy various experimental requirements. We report the design of new front-end DAQ and results of evaluation.

MADOCA was adopted for the control system of SACLA, and the MADOCA database system was designed as a copy of the database system in SPring-8. The system realized a high redundancy because the system had already tested in SPring-8. However the signals which the MADOCA system handles in SACLA are increasing drastically. And GUIs that require frequent database accesses were developed. The load of the database system increased, and the response of the systems delayed in some occasions. We investigated the bottle neck of the system. From the results of the investigation, we decided to distribute the access to two servers. The primary server handles present data and signal properties. The other handles archived data, and the data was mounted to the primary server as a proxy table. In this way, we could divide the load into two servers and clients such as GUI do not need any changes. We have tested the load and response of the system by adding 40000 signals to present 45000 signals, of which data acquisition intervals are typically 2 sec. The system was installed successfully and operating without any interruption which is caused by the high load of the database.
